;about

The invention relates to urban electric transport, in particular to the structures of the junctions of anchoring sections of a trolleybus and tram contact network equipped with a boom-type current collector.

The purpose of the invention is to increase the reliability of current collection at elevated speeds.

FIG. Figure 1 shows schematically a device for interfacing anchor sections of a contact network, a general view; otherwise FIG. 2 is a diagram of the mating of anchor sections; side view; in fig. 3 - tire adapter, general view; in fig. 4 - cross-section of the transition bus; in fig. 5 - pressure roller; in fig. 6 - view. And in FIG. 2; in fig. 7 is a view B in FIG. 2; in fig. 8 - hinge device, obsh, i view.

The device includes transient tires 1, placed under the supporting elements 2. Each tire 1 is suspended to the suspension cable 3 by means of separate insulated suspensions 4 and fixed on one side to the branch 5 of the contact wire with clamp 6, and on the other to anchor cable 7 with the help of the hinge 8.

At one end of the tire 1, a G-shaped lever 9 is fixed with a roller 10 installed with the possibility of pressing the counter branch 11 of the contact wire to the bottom of the tire 1, a U-shaped profile, the magnitude of which not being provided is provided by spacers 12.

Sliding insulated suspensions 4 rest on the guide rod 13 with an anvil 14 at the ends.

The electrical connectors 15 are suspended to the cable 3 on roller suspensions 16, consisting of rollers 17, brackets 18 and insulating strips 19.

The anchor cables 7 are suspended in the span to the holding cable 3 on the supporting strings 20, consisting of roller 21, bracket 22, slider insulator 23, link 24, clamp 25 and wire extension 26.

Tire 1 and contact wire 11, running inside it, are anchored in opposite directions through the deflecting rollers 27 to the load compensators 28 that maintain a constant tension in the contact wires.

The device works as follows.

When temperature changes, tire 1 and contact wire 11 have relative movements, while tire 1 is mixed together with branch 5 of contact wire fixed on it by means of clamp 6, and opposing branch 11 moves in the opposite direction without affecting the movement of tire 1 Unimpeded mutual movement of the tire and contact wire minimizes tension loss (up to 1%).

Claims (2)

1. A DEVICE FOR INTERFERING ANCHOR PLOTS OF THE TROLLEYBUS CONTACT NETWORK, containing adapter buses, according to the number of branches of one direction of contact wires, each of which is located under the supporting element, suspended from a supporting cable on sliding insulated suspensions and fixed on one side to the branch of the contact wire, and with on the other hand, to the anchor cable, and electrical connectors of the branches of the contact wires, with each adapter bus made with a cavity for passing the oncoming branch of the contact wire, different which, in order to increase the reliability of current collection at increased speeds, the device is equipped with a L-shaped lever fixed to one end of the adapter bus and a roller mounted on one end of it with the possibility of pressing the oncoming branch of the contact wire to the bottom of the bus, made V-shaped profile. 2. The device according to π. 1, characterized in that the adapter rail is attached to the anchor cable using a hinge. SU _w 1286449
